Consumers are starting to see lower loan rates thanks to the Federal Reserve's rate-cutting campaign. But for some credit-card holders, the benefits may be limited.

Since most credit cards are tied to banks' prime rate, which typically moves in lockstep with changes in the Fed's target rate, average rates on variable-rate credit cards have fallen to 12.18% from 13.97% in early September, according to Bankrate.com.
